CVE-2026-113373: Sonatype Nexus Repository 3 Pro account status bypass in SAML/OAuth2

CVE-2026-113373 · Severity: info · Published 2026-11-04

Sonatype Nexus Repository 3 Pro is a software component repository manager used by organizations to manage software dependencies and artifacts. An attacker with valid credentials at a connected identity provider (such as a corporate SAML or OAuth2 server) can bypass account lockout or disablement, regaining access to the repository and the permissions associated with their account. This allows a terminated or suspended employee, or an account compromised at the identity provider level, to restore access to sensitive software artifacts.

Vendors: Sonatype.

Technical details

When users authenticate via SAML or OAuth2/OpenID Connect, Nexus Repository 3 Pro does not validate whether the corresponding local account has been disabled or locked by administrators. An attacker with valid identity provider credentials for a named account can obtain a new authenticated session with the original account's roles, bypassing administrative account controls. The attack requires valid credentials at the external identity provider but no pre-existing Nexus session or Nexus-level privilege.
